Carbon dioxide emissions from the direct combustion of fuel, as well as that embodied in the production of electricity consumed in the building.
Carbon-dioxide emissions that include the greenhouse gas carbon dioxide as well as equivalent warming potential of several other major gases.
Median - In EnergyIQ, we typically use the median value to represent the central tendency of a set of benchmark data, rather than average (technically known as the "mean"). The median of a list of numbers can be found by simply arranging all the observations from lowest value to highest value and picking the middle one (or the average of the two middle values if the list contains an even number of entries). The average is the sum of all the values in the list divided by the number of values.
Thanks to Wikipedia, here is a practical example:
Suppose 19 paupers and 1 billionaire are in a room. Everyone removes all money from their pockets and puts it on a table. Each pauper puts $5 on the table; the billionaire puts $1 billion there. The total is then $1,000,000,095. If that money is divided equally among the 20 people, each gets $50,000,004.75. This is the average amount of money that the 20 people brought into the room. But the median amount is $5, since that would be the middle value in a ranked list. In a sense, the median is the amount that the typical person brought in. By contrast, the average is not at all typical, since nobody in the room brought in an amount approximating $50,000,004.75. By using the median, extreme outlying values don't skew the result.
This represents the percentage of buildings that have lower energy use, cost, or emissions than the user's building. This is not the same as a formal rating, such as that provided by the Energy Star Portfolio Manager tool.
The value of the energy delivered to the facility (or site), excluding that used to produce or deliver the energy. This is sometimes called "useful" energy.
The value of the energy delivered to the facility, including that required to produce and deliver the energy.
